131.9
ICD-9-CMThis code signifies an infection caused by the parasite Trichomonas vaginalis, affecting the genitourinary tract, where the specific site or manifestation of the infection is not documented. It typically presents as vaginitis in females and urethritis in males, though often asymptomatic.
This code is appropriate when trichomoniasis is diagnosed, but the medical record lacks specificity regarding the anatomical location (e.g., vaginal, urethral) or the patient's gender, or if the provider simply states "trichomoniasis" without further detail. It should be used when more specific codes for trichomoniasis are not supported by the documentation.
